PositionSizer View Post

Mike, I know I never really post here and I'm very very busy but I just wanted to kind of defend my product. Maybe this is my fault that my product got a bad rap or is misunderstood because I do not post enough on your forum. With the launch of my new product I will try and start adding value to your forum by showing how PositionSizer can help traders.

Thank you everyone.


I have been careful not to bash the product, but have simply explained why I prefer to use Excel. I am not trading hundreds of different instruments, but just a few, and they are all denominated in USD or Euro. With my Excel sheet and a Rule of Three I am as fast to enter any position, as I would with a position sizer.

This does not mean that the product is bad or offers no advantage. Position sizing is an important subject and has a huge impact on profitability. Once you have a reliable trading system, it is position sizing that determines the profits. I know the original Kelly paper and the book by Ralph Vince on The Mathematics of Money Management.

Serious vendors offer a free trial of their software. I am currently testing MultiCharts for 4 weeks and I have a rather favourable impression. This product has a 7 days trial period, which is a bit short to come to a conclusion. But at least there is no reason not to go for the trial. With the trial it is possible to judge whether the product is worth the money, and there will certainly be different opinions.
